CY7C65642-48AXC

Controllers Overview

The CY7C65642-48AXC is a USB 2.0 hub controller from the EZ-USB™ HX2VL family, designed for low-power applications with up to four downstream ports. It supports High Speed (480 Mbps), Full Speed (12 Mbps), and Low Speed (1.5 Mbps) data rates. The device features an integrated MCU with 2K ROM and 64 bytes RAM, multiple transaction translators (one per port), and an internal regulator requiring a single 5 V supply. Operating conditions range from 3.15 V to 5.25 V voltage and 0°C to +70°C temperature. It is housed in a 48-pin TQFP package measuring 7 × 7 mm.

Controllers Feature Summary

• Integrates four independent transaction translators for maximum bandwidth efficiency on full-speed and low-speed devices.
• Includes an internal power regulator that converts 5 V input to 3.3 V, reducing external component count.
• Supports configurable VID/PID and port settings via external EEPROM or pin strapping.
• Provides individual and ganged power switching modes with overcurrent detection capabilities.

Controllers Applications

• Docking stations
• Standalone hubs
• Monitor hubs
• Multi-function printers
• Gaming consoles

Controllers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with required clock sources and power configurations before procurement. Cross-reference datasheet revision numbers to validate feature availability and electrical characteristics.

Controllers Selection Notes

Select this model when designing USB 2.0 hubs requiring four downstream ports with dedicated transaction translators. Consider the 48-pin TQFP package for board layout requirements. Verify power supply constraints, as the internal regulator requires a 5 V input, while alternative packages support external regulation schemes.

Controllers Part Context

This component belongs to the EZ-USB™ HX2VL series of very low-power USB 2.0 hub controllers. It complements other variants like the CY7C65632 and CY7C65642-28LTXC by offering a high-performance solution with integrated transceivers and control logic optimized for cost-effective designs.

Controllers Replacement Considerations

CY7C65642-28LTXC: Offers identical functionality in a 28-pin QFN package instead of the 48-pin TQFP.

Controllers FAQ

How does the CY7C65642 handle speed translation?

It utilizes four independent transaction translators, one for each downstream port, allowing full 12 Mbps bandwidth for each connected full-speed or low-speed device without sharing bandwidth.

What are the power supply options for this controller?

The device supports both internal regulation, which requires a 5 V input, and external regulation, where a 3.3 V source can be provided directly to the VCC_A and VCC_D pins.

Can the number of active ports be configured?

Yes, the number of usable ports and their removable status can be configured via external EEPROM or through specific pin strapping settings during initialization.
